Stepping Out

213 independent analyses of this recording were submitted to AcousticBrainz. Fewer than half of them — 18% — put it in G minor, a key signature of 2 flats. The tempo printed above is the median of the 213 readings; 13% of them land within 2% of it, and the middle eight tenths of them run from 103.9 to 152 BPM. That is a recording the detector cannot settle on — the readings are spread far enough that the median is a summary of a disagreement rather than a measurement anybody should trust to the decimal.

At 132.2 BPM one beat lasts 453.9 milliseconds, so a sixteenth note is 113.5 ms and a dotted eighth 340.4 ms — the delay times for this recording. Counted half as fast it is 66.1 BPM, counted twice as fast 264.4. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 436 Hz, which is 16 cents below concert A at 440 Hz — the sort of drift a tape machine or a slightly different mastering leaves behind. That is a fact about this transfer of the music, not about how it was played.

The dynamic complexity of the recording measures 2.54 dB: that is how far the level wanders from its own average, so a small number means a loud, flat master and a large one means a recording that still breathes. Its average loudness is 0.767 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
